What is Network Segmentation? Virtual & Physical Segmentation | UpGuard

This report is an informational guide on network segmentation and micro-segmentation, outlining how dividing networks into segments improves security (by containing lateral movement and reducing attack surface), performance, and monitoring; it explains physical vs. virtual segmentation (including VLANs and software-defined networking), connects segmentation to zero-trust principles, lists common drawbacks (cost, complexity, misconfiguration risk), and briefly promotes UpGuard’s cybersecurity services.
